http://s3.运维网.com/wyfs02/M00/12/81/wKioL1MKKM_hWulJAARhOmwv3HQ253.jpg
修改数据库文件
# vi /etc/my.cnf
添加一行配置
innodb_file_per_table=1
四.安装nrpe扩展组件
# cd /usr/local/src/
# tar zxvf nrpe-2.15.tar.gz
# cd nrpe-2.15
# ./configure
http://s3.运维网.com/wyfs02/M02/12/80/wKiom1MKKRWBzFlRAAIkR7Tn9jw349.jpg
(1) 安装check_nrpe 这个插件
# make all
# make install-plugin
(2) 安装deamon
# make install-daemon
(3) 安装配置文件
# make install-daemon-config
(4) 编辑nrpe配置文件
lianglab nrpe-2.15]# vim /usr/local/nagios/etc/nrpe.cfg
默认为allowed_hosts=127.0.0.1 修改为 allowed_hosts=127.0.0.1 10.1.10.132
http://s3.运维网.com/wyfs02/M02/12/81/wKioL1MKKR6gyYRoAABtwcFqzOo964.jpg
5) 启动nrpe
# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
#
6) 查看NRPE 是否已经启动
# netstat -nltp | grep nrpe
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN 14461/nrpe
tcp 0 0 :::5666 :::* LISTEN 14461/nrpe
#
7) 测试NRPE 是否则正常工作
之前安装了check_nrpe 这个插件用于测试,现在就是用的时候.执行
# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
NRPE v2.15
# /usr/local/nagios/libexec/check_users -w 5 -c 10
USERS OK - 4 users currently logged in |users=4;5;10;0
#
# /usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
OK - load average: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0; load5=0.000;10.000;25.000;0; load15=0.000;5.000;20.000;0;
五.安装ndoutils数据库插件
# tar zxvf ndoutils-1.5.2.tar.gz
# cd ndoutils-1.5.2
# ./configure --prefix=/usr/local/nagios --enable-mysql --disable-pgsql --with-ndo2db-user=nagios --with-ndo2db-group=nagios
# make
# make install
复制配置文件
# cat config/ndo2db.cfg-sample|grep lock_file
lock_file=/usr/local/nagios/var/ndo2db.lock
#
# cp ./config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
# cp ./config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
# cp ./config/ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg
# cp src/ndomod-3x.o /usr/local/nagios/bin/
# cp src/ndo2db-3x /usr/local/nagios/bin/
# chmod 774 /usr/local/nagios/bin/ndo*
# chown nagios:nagios /usr/local/nagios/bin/ndo*
# chown nagios:nagios /usr/local/nagios/etc/ndo*
# cp ./daemon-init /etc/init.d/ndo2db
# chmod +x /etc/init.d/ndo2db
#
配置开机自动启动
# chkconfig --add ndo2db
# chkconfig --level 345 ndo2db on
# /etc/init.d/ndo2db start
ndo2db already started...
#
# /etc/init.d/ndo2db status

至此2.5安装完毕，需要进行web页面配置，初始化数据库。
接下来就是页面配置部署了
先访问http://10.1.10.132/centreon登陆安装页面
安装欢迎界面，点next下一步
http://s3.运维网.com/wyfs02/M01/12/80/wKiom1MKLYmAOfkfAADpLwxKlP8560.jpg
基本环境检查，一般检测通过才可继续安装，点击next
http://s3.运维网.com/wyfs02/M00/12/81/wKioL1MKLWODKNBTAAE2I9oYEfs201.jpg
安装监控组件，选择nagios.配置为
/usr/local/nagios
/usr/local/nagios/bin/nagiostats
/usr/local/nagios/share/images
http://s3.运维网.com/wyfs02/M02/12/80/wKiom1MKLYnRPHRRAAF2QcaV7I4174.jpg
选择代理模块
配置为/usr/local/nagios/bin/ndomod.o
http://s3.运维网.com/wyfs02/M00/12/81/wKioL1MKLWSyTYFhAAEWT_VYIPQ339.jpg
设置管理员密码和邮箱，全部必填。
http://s3.运维网.com/wyfs02/M01/12/81/wKioL1MKLWSh47u7AAFAFDo1KIY098.jpg
配置数据库，填写mysql的root密码和应用库密码。
http://s3.运维网.com/wyfs02/M00/12/80/wKiom1MKLYmgzUZiAAHhd04R-Os707.jpg
如果上面配置没问题的，就初始化数据库等相关配置
http://s3.运维网.com/wyfs02/M02/12/81/wKioL1MKLWTh_07fAAFi8aSBgeE629.jpg
http://s3.运维网.com/wyfs02/M02/12/80/wKiom1MKLYqTY3r-AAFrtbQvTp0493.jpg
自动跳转到2.5.0登陆欢迎界面。
http://s3.运维网.com/wyfs02/M01/12/81/wKioL1MKLWShSmnWAACcykVutTo218.jpg
登陆后正常应该先选择nagios生成配置文件，现在页面没有直接写明nagios配置项了。
找到如下菜单
Configuration-->Monitoring Engines-->Generate
选择Export导出默认配置，正常情况应该是OK。
5个选项全勾选上，选择Export导出配置文件以及覆盖文件和重启nagios:
http://s3.运维网.com/wyfs02/M02/12/80/wKiom1MKLhzzVhvLAAM2iTVIaco805.jpg
导出配置和重启服务正常
http://s3.运维网.com/wyfs02/M01/12/80/wKiom1MKLY_ymG7xAAHPiqvYjDc438.jpg
查看nagios的etc目录是不是新增加了很多配置文件：
#ls -al /usr/local/nagios/etc/
http://s3.运维网.com/wyfs02/M00/12/81/wKioL1MKLWnhjiooAAaGXHmtD8Y454.jpg
重启相关服务：
# /etc/init.d/centcore start
Starting centcore: [确定]
# /etc/init.d/centstorage start
Starting centstorage: [确定]
# /etc/init.d/ndo2db stop
Stopping ndo2db: head: 无法打开"/usr/local/nagios/var/ndo2db.lock" 读取数据: 没有那个文件或目录
done.
# /etc/init.d/ndo2db start
Starting ndo2db: done.
#
点击 Configuration-->Centreon-->Pollers查看
这样Pollers就能看到进程号了
到处，Centos6.5下安装Nagios4.02+Centreon-2.5.0监控环境搭建完成。
